M3AS wireless microphone
One to Two Wireless Series
This is a one to two wireless microphone with a high-definition LED LCD display screen. It has powerful functions such as automatic frequency hopping and noise suppression, and is suitable for KTV entertainment, wedding hosting, and other places.
Product Features:
1. Industry first automatic frequency hopping technology to avoid interference: When encountering strong external interference, it will automatically hop to a frequency point with no or less interference. The frequency hopping function can be switched on and off to avoid repetitive and tedious manual operations;
2. Adopting four built-in EQ sound effects modes, which can be freely switched to the desired mode;
3. Equipped with infrared automatic frequency matching function, it can quickly synchronize the microphone to the working channel of the receiver;
4. Adopting automatic mute technology, the microphone will automatically mute within 3 seconds after leaving the hand and coming to a standstill (can be placed in any direction or angle), and automatically enter standby mode after 5 minutes to save energy;
5. Adopting a lock screen function to prevent human error;
6. Built in howling suppression function circuit, easier to debug;
7. Adopting the function of automatically searching for interference free channels;
8. In an ideal environment, the operating radius should reach or exceed 120 meters, making it suitable for various requirements.
Applicable scenarios: entertainment KTV private rooms, private clubs, high-end villas, multifunctional halls, conference rooms in enterprises and institutions
